Cal. C125 is a modular automatic movement with a GMT function. Built on the Soprod A10-2 base (now known as M100), this movement differs from other GMT movements in that the “local” time (quick-set hours) is the 24 hour hand rather than the standard 12 hour hand. The date is similarly “tied” to the regular timekeeping hands, and pulls the GMT time along with it. This is due to the fact that the module uses the day mechanism rather than a unique gear train.
The GMT module increases the movement thickness from 3.6 mm to 4.1 mm and the stem height from 1.5 mm to 2.0 mm. Interestingly, Hager claims that this movement is 5.67 mm thick, uses Novodiac rather than Incabloc, and has 40 hours power reserve.
Formerly known as Calibre SOP 9384/A10-2, the movement was renamed Cal. C125 in 2016 when Soprod renamed the A10-2 to M100.
Cal. C125 is used by Oak & Oscar and Hager.
